Opinion

OPINION

TEHAN, District Judge.

This is a civil action for a declaratory judgment to invalidate two United States patents. L. F. Strassheim Company, a Wisconsin corporation doing business as the Bowling Green Chair Co. is the plaintiff, and Gold Medal Folding Furniture Company, also a Wisconsin corporation, is the defendant. The defendant has counterclaimed for injunctive relief and damages arising from the plaintiff’s infringement of the two patents. The cause of action for a declaratory judgment arises under Title 28 U. S.C. § 2201, with jurisdiction conferred on this court by Title 35 U.S.C. §§ 101, 102, 103 and 171. The defendant’s cause of action for patent infringement arises under Title 35 U.S.C. § 281, with jurisdiction conferred by Title 28 U.S.C. § 1338(a). Venue is properly laid in the Eastern District of Wisconsin.

Defendant is the owner of the entire right, title and interest in United States Patent 2,699,816 (hereinafter referred to as ’816), applied for December 28, 1953 and issued January 18, 1955 on a “Chair Back,” and United States (Design) Patent D189343 (hereinafter referred to as ’343), applied for December 2, 1958 and issued November 29, 1960 on a “Collapsible Chair”, both assigned to the defendant company. The patented features of the chair at issue here are [710]*710the fitting of a flexible fabric back rest (’816) and the design of the armrest and upright supporting spindle (’343).

Plaintiff claims invalidity of the two patented features as well as misuse of patent ’816. One basis of its claim of invalidity against each patent is obviousness, under 35 U.S.C. § 103, which it seeks to prove by prior art; in addition, the plaintiff asserts public use of the patented feature (’816) of the chair more than a year prior to filing of its application for the patent and misrepresentation by the defendant in applying for patent ’816. The plaintiff has admitted infringement — but not of a wilful and wanton nature — insofar as the patents are declared valid by this court.

The matter was tried here on June 13-15, 1967. Time was allowed for preparation and submission of briefs, followed by oral arguments on February 21, 1968.

Patent ’816 relates to the back of a director’s-type folding chair in which the side armrest assemblies, including their backposts, can swing “outwardly and downwardly” when the restraining canvas fabric back panel is removed from the backposts. The back panel contains loops formed along the entire edge of both ends. Each loop slips over its corresponding back post, leaving an acorn at the top of each post exposed. Each post has a notch just below the acorn, forming an upwardly facing shoulder. A welt or hem formed on the inside of each panel, slips into the notch, thereby inhibiting slippage of the back panel. The back panel is uniformly tensioned along its height on the posts and the tension of the panel is evenly distributed along each post.

Director’s chairs without the instant invention, had been made for several years by defendant and its competitors prior to the application for the '816 patent. The sagging of the back panel, prior to the ’816 invention, was, however, a problem for the industry. Numerous attempts had been directed at its solution, as for example, by tacking or using glove fasteners or clips, taping, sewing the top of the loops closed over the acorn of the post, or by tapering the backposts, The plaintiff itself tried applying adhesive or “varnish which was not slippery” to the posts. But none of these measures seemed fully to correct the problem of a sagging back panel.

INVALIDITY.

The plaintiff asserts invalidity of ’816 because of obviousness and lack of invention under 35 U.S.C. § 103 1 in view of the patented prior art of U.S. Patent Nos. 1,739,552 (“Kidder”), 2,702,586 (“Borgfeldt”) and 2,582,864 (“Git-tings”). The latter disclosed all features of the ’816 patent, except for the notch and welt feature disputed here. In the Kidder patent, there is provision for a notch, and in the Borgfeldt patent for a reduced portion of the back rest, each of which indentations seem to relate to the back panel in a manner suggestive of that in the ’816 patent.

It is well-established that a patent is presumed valid and the plaintiff therefore assumes a heavy burden in challenging its validity. Accordingly, every reasonable doubt should be resolved here in favor of the defendant. Devex Corp. v. General Motors Corp., 321 F.2d 234 (7th Cir.1963). The presumption of validity is increased where an infringer in a suit for infringement cites and relies upon prior art which is no more pertinent than that considered by the Patent Office before issuing the patent. It is immaterial that the Borg[711]*711feldt patent was not then before the office when it approved the defendant’s patent insofar as it is in no way more pertinent than the Kidder patent, which was before the office.

To arrive at the invention of the ’816 patent, more was involved than simply putting a groove in the back posts of a prior art chair. To quote the defendant "[i]t is just not a matter of putting a little notch and offering some resistance; this really locked and this is the invention.” (Transcript, Oral Argument, February 21,1968, p. 32).

Nothing in the Kidder patent nor in the earlier Gittings patent teaches us how a hidden welt in the inside of the back panel could be made to lock in a groove in the back post as in the ’816 patent while at the same time permitting even tension of the fabric along the chair’s backposts. That is, neither the Kidder patent 1,739,552 nor the Borgfeldt patent 2,702,586 shows or suggests the invention of a hidden, inside welt in an end loop of a back panel, extending substantially the full height of the panel, which can be slipped over the back-posts so that the welt locks securely in a groove in the backpost, thereby providing even tension and distribution of force along the entire height of the back panel. Moreover, in both the grooved Kidder and Borgfeldt patents, contrary to ’816, the tension of the back panel is localized at the points on the fabric where it is connected to the back posts.

Finally, the Borgfeldt patent 2,702,586 relied on by plaintiff is not a folding chair of the type having laterally outwardly swingable back posts.
